## In short

Garu Seonsaeng Drinkable Fresh Soy Milk Black Soybean is a powdered soy milk stick made with Korean black soybeans and sun-dried salt. I mixed two sticks with 200 ml of cold water as a coffee alternative at breakfast; it dissolved smoothly and tasted nutty, with an adjustable thickness depending on the water amount.

I received this product and used it.

As the weather got warmer, I often had only an iced Americano in the morning because I had little appetite. Coffee on an empty stomach gave me heartburn and left me hungry, so I tried Garu Seonsaeng Drinkable Fresh Soy Milk Black Soybean as an alternative.

## What ingredients does it contain?

The two ingredients I found were Korean black soybeans and sun-dried salt. It was introduced as having no added sugar, and its simple ingredient list stood out to me.

It is said to contain whole Korean soybeans, from the skins to the soybean pulp. The original post said one serving provides 8.1 g of protein, but it did not specify how many sticks that figure is based on.

## How were the powder sticks for storage and carrying?

The homemade soy milk I used to drink tasted good, but its short use-by date meant I often could not finish it and had to throw it away. These were convenient powder sticks that I could mix only as needed, and they did not feel burdensome to carry in my bag.

## Does it dissolve well in cold water and taste nutty?

When I opened a stick, the powder looked pale green rather than black.

I mixed two sticks with 200 ml of water. It dissolved smoothly after a few stirs with a spoon in cold water, and I could taste the distinctive nuttiness of black soybeans along with a deep, homemade-soy-milk-like flavor. I liked that changing the amount of water let me drink it either thick or thin.

## How can it be used as soy milk and kongguksu?

- For black soybean soy milk, mix one stick with 100–120 ml of cold water. Adjust the amount of water to your taste.
- For kongguksu (noodles in cold soybean soup), cook somyeon (thin wheat noodles) or konjac noodles first, then mix two or three sticks thickly with cold water and pour it over the noodles.

The “30-second kongguksu” introduced in the original post is a way to make the soybean soup once the noodles have already been cooked. The ratio I personally mixed and drank was two sticks with 200 ml of water.

## Where was this product introduced as being sold?

The original post, written on Jun 29, 2026, introduced it as a limited-sale product at Olive Better and the Olive Young online mall. It listed three flavors—black soybean, matcha, and mugwort—and I tried the black soybean one.
